The Solution

  • API Testing - Manual
  • WCF Test Client
  • Soap UI
  • API Testing - Automation
  • Soap UI
  • Microsoft Web Test
  • Using Programming Language

WCF Client

  • Windows Communication Foundation
  • Microsoft .NET framework and user friendly
  • Give input, invoke method and analyze results
  • Advantages
  • Interoperability
  • Security and Reliability
  • Disadvantages
  • Pending requests aborted when closed
  • Automatically generated values and cumbersome to use

The Solution – Soap UI

  • Simple Object Access Protocol
  • Communicates over HTTP
  • Suite execution using user interface
  • Suite triggers from automation build / command prompt
  • Advantages
  • Extend HTTP for XML messaging
  • Platform- and language-independent
  • Disadvantages
  • No mention of security facilities.
  • Do not hold any state references to remote objects

The Solution – Microsoft Web Test

  • User performs a set of operations
  • Good for simpler web services and straightforward functionality
  • Suitable for performance testing
  • Advantages
  • Easy test scripts creation using test recorder
  • Edit recorded tests to tailor to specific needs
  • Disadvantages
  • Not much validation logic can be put into the tests
  • High Volume tests were not at all executed in the test suite
  • Maintenance is difficult

Current Approach – Testing Framework

  • Stable automation

framework using C#

  • Simple, object-
  • riented language
  • Test Framework

15 PNSQC 2015

SLIDE 16

Current Approach – Testing Framework

  • Advantages
  • C# framework is tool independent
  • Ease-of-development, rich class library, functions
  • End to End solution with DB validations
  • Anyone can contribute to the framework
  • Interoperability
  • Disadvantages
  • Depends on .NET framework. Library not found in .NET difficult to implement
  • C# doesn’t come up with open source technologies and operating systems

Challenges in API Testing

  • Parameter Combination, Call Sequencing
  • No GUI - difficult to provide inputs
  • Not easy to validate output
  • Exception handling function

API Testing -- Advantages

  • Much better quality product, ensuring the data access
  • Simple security compliance testing
  • Complete functionality allows for easy future expansion of the application
  • Structured way of testing, makes automation more feasible

API Testing -- Disadvantages

  • No Encryption
  • Increasing Tooling needs
  • Straightforward reason for failing API is not known like GUI
slide-21

End to End Testing:

  • Extension of all BVT scenarios to test end to end functionality
  • Service call for different APIs in a single method
  • Needs a good coding style and capturing of exact results

Integration Testing

  • Testing of different systems as one
  • Covering BVT and FVT functionality by considering all system

behavior
